Duct Detector Remote Test Switch Locations

The duct detector should when possible be located a minimum of six duct widths downstream from a source of turbulence bends inlets or deflection plates.

Duct detector remote test switch locations.

Wiring diagrams for duct smoke detectors. For 2 wire detectors the led illuminates red for alarm. For 4 wire detectors the rts151key test station features a multi colored led that alternates between steady green and red. The rts151 and rts151key remote test stations are automatic fire detector accessories designed to test duct smoke detectors from a convenient location.

Since the requirement for tying in duct detectors is in 907 fire alarm and detection systems the duct detector rule 907 11 doesn t apply to what you re doing. Yes if the duct detector cannot be reset at the facp or annunciator then a separate test reset station will need to be installed for resetting the duct detector per nfpa 72 section 23 8 5 4 6 4. At these locations air flow is less turbulent and the air smoke mixture should be more homogenous refer to nfpa 90a 72 and 101 for more information. The wiring diagram graphics here are for illustration purposes only.

Always follow duct detector manufactures instructions and code for wiring.
